UNITED STATES MILTON S. DUNKELBERGER, OF DAYTON, OHIO.

TOY RAILWAY TRACK.

Application filed March 12, 1923.

T all whom it may concern:

Be it known that I, MILTON S. DU'NKEL- nnnonn a citizen of the United States, residing at bayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Toy Railway Tracks, of which the following is a specification.

The principal object of my invention is to provide for toy railwayengines and cars, a strong and well formed track which may be readily laid and thereafter easily bent to provide the desired curves.

It is another object of my invention to provide a toy track which may be compactly shipped to its destination.

Other important and incidental objects will be brought out in the following specification and particularly set forth in the subjoined claim.

The preferred form of embodiment of my invention is illustrated in the accompanying drawings, of which Figure 1 is a perspective view of my improved toy track. Figure 2 is a perspective view of one of the rail-clamping pieces. Figure 3 is a side view of a portion of a rail showing how it is secured to a tie by one of the clamping pieces. And Figure 4 is a cross sectional view taken through the same.

Referring to the accompanying drawings for a detailed description of the form of embodiment of my invention illustrated therein, the numeral 1 designates a tie constructed There are three of these ties shown in Figure 1, to each one of which there are secured by nails 2 or other fastening elements, a series of rail-clamping pieces 3. There are three of these pieces shown attached to each tie in Figure 1, to receive three rails 4: for a third rail electric system.

Each one of the clamping pieces 3 preferably comprises a strip of spring steel or other suitable resilient metal which crimped by a die in a stamping machine to the shape shown in Figure 2. Eachclamp- Serial No. 624,618.

ing piece is bent bythe die to form two humped portions 5, 5 between which there is a rail receiving groove 6, the ends of the piece being turned outwardly to provide feet 7, 7 containing apertures 8, 8 to receive the nails 2, 2by which the piece is secured to a tie.

The rails 4 are preferably made of bars of spring steel or other suitable material which may be readily bent for compactshipment. lVhen it is desired to lay the track, a child may easily slip these railsinto the grooves 6 of the clamping pieces 5 after they have been secured to the track'by the fastening elements 2.

After the rails are inserted in the grooves 6 of the clamping pieces 3, they may be easily bent to form a desired curve in the track. This result is not only due to the springy quality of the steel rail, but also to the yielding property of groove-containing portion of the clamping piece. It would be difficult to bend the rail if it were inserted in a groove in the tie, or secured thereto by rigid, non-yielding fastening elements. The rails may also be longitudinally adjusted in the clamping pieces for the proper connection to other rails.

It will thus be seen that my rails may not only be compactly shipped and thereafter easily secured to the ties, but they may be easily bent after being inserted in the clamping pieces, or longitudinally adjusted in them.

Having described my invention, I claim:

A toy railway track comprising a series of ties, rails therefor comprising bars of spring metal, and clamping pieces secured to said track, each clamping'piece being crimped to form two hump portions with a groove be tween them to receive a rail.

In testimony whereof I have hereunto set my hand this 9th day of March, 1923.
